Well, I can only speak for myself so here's why I prefer Beats.

I listen to a crapton of music, videos and games in HD on my computer. I sit in front of my monitor for hours after hours and after awhile that "just a bit more muffled than Beats" noise starts giving you a headache, while Beats are clear all day long. You really pay for great quality and duration, others are great replacements and have better seals for bass leak but they don't even out the distribution of vocals to bass.

Just my take on it but I always recommend and tell people to NOT buy Beats if it'll be something that breaks your pockets, but buy them if you have the cash and the necessity.
